Facebook shares its population density data with Red Cross's Missing Maps, a project that aims to improve mapping data for at-risk communities. Facebook donates data related to computer visioning and satellite imagery, helping Missing Maps fill in gaps in their work.
Missing Maps conducts Mapping Parties in cities across the world to use satellite data, like that provided by Facebook, to update their map information. Red Cross can also gain direct access to this data via the partnership.
This partnership between Red Cross and Facebook allows humanitarian organizations to more quickly identify communities and individuals in unmapped areas. This allows for the more efficient allocation of aid and resources, particularly during crisis events when vulnerable populations are often unrepresented on maps and therefore harder to reach.
